DISHWASHING DEVICE.

Application filed February 12, 1921. Serial 110. 444,467.

To all whomit "my concern.

Be it known that I, J osnPH HAUK, a citizen of the United- States, andresident of Shorewood, in the county of Milwaukee and State ofWisconsin, have invented new and useful Improvements in DishwashingDevices, of which the following is a description, reference being had tothe accompanying drawings, which area part of this specification. I

The invention relates to motor driven dish-washing machines. Inlocalities where a supply of water under pressure is not available, butwhere power may be readily furnished for running a dish-washing machine,it is desirable to supply the machine with water under pressure and tostore a supply of rinsing and soapy water for use in the machine. It isthe object of this invention to meet this condition by providing adish-washing machine in which the power for operating the machine isused to supply rinsing water and soapy water under pressure for use inthe machine from storage tanks upon the machine which may bereadilycharged and emptied of their contents.

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a vertical sectional view taken through adevice embodying the invention; Fig. 2 is a plan view of the machine;Fig. 3 is a section taken on the line 33 of Fig. 1; Fig. 4 is aside viewof the machine, parts being broken away and parts being shown insection; Fig. 5 is a detail side view of the machine showing the storagetanks in elevation and parts of the fluid connections being shown insection.

In the drawings the numeral 6 designates a receptacle supported on aspider 7 carried by upright legs 8 which are braced intermediate theirends by cross-frame members 9 upon which the base plate 10 is mounted.An electric motor 11 is mounted on the base 10 and drivingly connectedby a belt 12 and pulleys 13 with a shaft 14. The shaft 14 carries apulley 15 connected by a belt 16 to a pulley 17 on a shaft 18 Journalledin a bracket 19 secured to a sleeve bearing 20 which is mounted on andextends below the spider 7. The shaft 18 is provided with a worm 21meshing with a worm wheel 22 upon an upright shaft 23 journalled in thebearing sleeve 20. The upper end of the shaft 23 supports an armedbracket 24 car'- rying a dish-carrying basket 25 which is mounted withinthe receptacle 6 and re- 0 volved through the belt and gearingconnections just described on a rotation of the motor 11. 'hile a motoris preferred it will be understood that any suitable source of power maybe used to drive the shaft 14. 5

A pair of storage tanks 26 and 27 for holding soapy water and rinsingwater, respectively, are connected to a hooked bracket 28 engageablewith the upper edge of cylindrical shell 29 which encloses the opeartingmechanism disposed between the spider 7 and the base 10. This hookconnection permits the tanks to be shifted or bodily moved by hand fromone side to the other of a discharge spout or drain 30 from thereceptacle 6 whereby the water or washing fluid in the receptacle 6 isconducted from said receptacle back into that tank whose open end ispositioned below the spout. Pipes 31 and 32 connect the tanks 26 and 27with a valve fitting 33 in which is disposed a three-way valve 34 havinga passage 35 to connect either one of the tanks 26 and 27 with a drain36 and a flexible pipe or hose 37.

The pipe 37 leads to the inlet 38 of a centrifugal pump 39 the rotor ofwhich is mounted on the shaft 14 and driven thereby to force the wateror washing fluid through a pipe 40 which connects with pipes 41 and 42.I 7 9c The pipe 42 is preferably flexible and 0on meets with a conduit43 carried by a cover 44 which is hingedly connected at 45 with thereceptacle 6. A rotatable spray nozzle .46 is secured to the end of'thepipe 43 and directs. the spray of cleansing fluid down upon the dishesin the basket 25. The 1nlet pipe 47 i journalled in a nipple 48 andcarries a flange portion 49 running on ball bearings 50 seated in arecess in the upper no end of the nipple 48. and a second series of ballbearings 51 are interposed between the lower end of the nipple 48 and acollar 52 on the pipe 47. The nozzle member 46 similar to well knownsprinkler heads rotated by the reaction of a jet of water has aninclined spray pening 53 at one end and a weighted portion 54 at theother end and the water under pressure from the pump 39 passing throughthe pipes 40, 42 and 43 and into the nozzle. serves to rotate the samewhile the spray is directed through the opening 53 down onto the dishesin the basket 25.

A nozzle 46', similar to the nozzle 46, is similarly mounted upon theupper end of the pipe 41 and is disposed below the basket 25 so that thewater from the pump passing through the pipe 41 is delivered by thenozzle, during its rotation, against the bottom portions of the dishesin the basket 25. With this construction, when the motor is started inoperation and the dishes are placed in the basket 25 the nozzles 46 and46 direct their streams toward the top and bottom portions of the basketand against the dishes therein to efliciently clean them,the nozzlesbeing eccentrically located with respect to the axis of rotation of thebasket so that the spray may reach all the dishes in the basket. and asthe water passes to the bottom of the receptacle it returns by way ofthe drain 30 to either of the storage tanks 26 or 27 from which it isbeing drawn by the pump. When hot soapy water is desired the tanks aredisposed inthe position shown in Fig. 5, and after this water has beenapplied the valve 34 may be turned to shut, off communication betweenthe pipe 31 and the pipe 37 so that the soapy water in the system may bereturned to the tank 26, and then the tanks may be shifted so that thetank 27 comes under the spout 30 and the valve 34 turned to bring thepipe 32 into connection with the pipe 37, thereby shut-- ting ofl'connection between the pump and the tank 26 and establishingcommunication between the tank 27 and the pump so that rinsing water maybe supplied to the washing nozzles of the machine, and after-the rinsingis completed the valve 34 may be turned to shut off communicationbetween both tanks 26 and 27 and the pipe 37 to return the rinsing waterto the tank 27 from there'ceptacle 6. After the washing is completed thetanks 26 and 27 may be emptied, one at a time, by turning the valve 34to the proper position and by turning the drain cock 36 to'openposition.

I desire it tobe understood that this invention is not to be limited toany particular form or arrangement of parts except in so far as suchlimitations are specified in the claims. 7

What I claim as my invention is:

1. In a dish-washing machine, the combination of a receptacle, adish-carrying basket mounted therein, a nozzle directing washing fluidupon the dishes in said basket, a discharge spout at the bottom of thereceptacle, a support, a pair of fluid supply tanks mounted on saidsupport and movable so that one or the other may be dis posed below saidspout, a motor-driven pump mounted on the machine, piping con nectingsaid pump with said tanks, a valve in said piping controlling the flowof fluid from either one of said tanks to'said pump, and pi ing fromsaid pump to said nozzle to con not the fluid under pressure to the ame.

2. In a dish-washing machine, the combination of a receptacle, adish-carrying basket mounted therein, a nozzle directing washing fluidupon the dishes in said basket, a drain for said receptacle, a pair offluid supply tanks movable with respect to the drain for selective use,a motor-driven pump, piping connecting said pump with said tanks, avalve in said piping controlling the flow of fluid from either one ofsaid tanks t said pump, and piping from said pump to said nozzle toconduct the fluid under pressure to the same. v
